Detailed implementation mode

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] The present invention discloses a double printing roller seamless film press. As Figures 1 to 8 shown, the present invention has the effect of facilitating film pressing and printing roller pressing, and includes a left frame 1, a middle frame 2, and a right frame 3; a mother film placing device 4 and a white film placing device 5 are arranged on the right frame 3; a mother film winding device 6 and a white film winding device 7 are arranged on the left frame 1; a first pressing roller 8 is arranged inside the right frame 3; a preheating roller 9 is arranged on one side of the first pressing roller 8; a first printing roller 10 is further arranged on the right frame 3; a first moving roller 11 is arranged on one side of the first printing roller 10; a first telescopic frame 12 is arranged outside the first moving roller 11 and the first telescopic frame 12 is connected to a first cylinder 13; a second printing roller 14 is arranged on the middle frame 2; a second moving roller 15 is arranged on one side of the second printing roller 14; a second telescopic frame 16 is arranged outside the second moving roller 15 and the second telescopic frame 16 is connected to a second cylinder 17.

[0015] By adopting the above technical solutions: The master film is placed on the master film placing device 4, and the white film is placed on the white film placing device 5; during film pressing, for the master film that needs to be preheated, it can pass between the preheating roller 9 and the first pressing roller 8, and the master film is preheated by the preheating roller 9. The first pressing roller 8 can be displaced to adjust the distance between it and the preheating roller 9, so as to preheat the master film according to the actual situation. If the master film does not need to be preheated, it can be not preheated. There is no nickel plate on the first printing roller 10 and the second printing roller 14, and the first printing roller 10 and the second printing roller 14 are respectively heated to 120 - 140 degrees Celsius; the master film and the white film enter between the first printing roller 10 and the first moving roller 11 for film pressing, and after film pressing, they enter between the second printing roller 14 and the second moving roller 15 again for film pressing. Finally, the master film is wound on the master film winding device 6, and the film-pressed white film is wound on the white film winding device 7.

[0016] During plate pressing, there is a nickel plate on the first printing roller 10 and the second printing roller 14, and the first printing roller 10 and the second printing roller 14 are respectively heated to 120 - 140 degrees Celsius. When the white film passes through the cold area 27 on the first printing roller 10, no pattern is printed on the white film in contact with the cold area 27, and when passing through the second printing roller 14, the pattern on the nickel plate is printed onto the white film in contact with the cold area 27 of the first printing roller 10. When passing through the first printing roller 10 and the second printing roller 14, the pattern on the nickel plate is printed on the white film to perform plate pressing on the white film; the first moving roller 11 can adjust the distance between it and the first printing roller 10 through the first cylinder 13 and the first telescopic frame 12, and the second moving roller 15 can adjust the distance between it and the second printing roller 14 through the second cylinder 17 and the second telescopic frame 16, so as to adjust according to the thickness of the white film and the master film and the actual situation to meet the requirements of film pressing and plate pressing.

[0017] As Figure 2 shown, a first guiding roller 18, a fixed roller 19, and a second guiding roller 20 are arranged on the right frame 3; a first roller frame 21 is arranged outside the first pressing roller 8; the first roller frame 21 is connected to the right frame 3 through a first connecting bar 22; the first roller frame 21 is connected to the telescopic shaft of the third cylinder 23; a first adjusting roller 24 is arranged below the first cylinder 13; the first adjusting roller 24 is located between the second guiding rollers 20.

[0018] As Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 shown, there is a right groove 25 on the right frame 3; one end of the first telescopic frame 12 is matched with the right groove 25; there is a middle groove 26 on the middle frame 2; one end of the second telescopic frame 16 is matched with the middle groove 26.

[0019] By adopting the above technical solution: The first guiding roller 18 guides the mother film so that the mother film moves within the right frame 3. For the mother film that needs to be preheated, it enters between the preheating roller 9 and the first pressing roller 8 after passing through the two first guiding rollers 18 on the right side. When the telescopic shaft of the third cylinder 23 extends, it can make the first roller frame 21 rotate around the first connecting bar 22, thereby adjusting the position of the first pressing roller 8 and further adjusting the distance between the first pressing roller 8 and the preheating roller 9 to better preheat the mother film. When the mother film does not need to be preheated, the mother film enters between the first printing roller 10 and the first moving roller 11 after passing through the first guiding roller 18 and the fixed roller 19.

[0020] The first adjusting roller 24 is convenient for adjusting the white film to prevent the white film from wrinkling; One end of the first telescopic frame 12 is matched with the right groove 25, so that the first telescopic frame 12 moves along the right groove 25 to adjust the position of the first moving roller 11; One end of the second telescopic frame 16 is matched with the middle groove 26, so that the second telescopic frame 16 moves along the middle groove 26 to adjust the position of the second moving roller 15.

[0021] As Figure 2 、 Figure 3 、 Figure 6 As shown in the figure, there are cold zones 27 on both the first printing roller 10 and the second printing roller 14, and nickel plates are arranged on the outer sides of the first printing roller 10 and the second printing roller 14 during plate pressing; A third guiding roller 28 is arranged below the first printing roller 10; A fourth guiding roller 29 is arranged below the second printing roller 14.

[0022] By adopting the above technical solution: During plate pressing, the nickel plate is located on the outer sides of the first printing roller 10 and the second printing roller 14, and both ends of the nickel plate are located on the cold zone 27, so that black edges can be prevented from being generated on the white film during plate pressing. The white film passing through the cold zone 27 of the first printing roller 10 is plate-pressed on the hot zone of the second printing roller 14 to plate-press the white film. By setting the cold zone 27, black edges can be prevented from being generated on the white film. After being plate-pressed by the first printing roller 10 and the first moving roller 11, the white film enters the middle frame 2 through the third guiding roller 28 and the fourth guiding roller 29.

[0023] As Figure 3 As shown in the figure, a second adjusting roller 30 is arranged above the second telescopic frame 16; A fifth guiding roller 31 is arranged on one side of the second adjusting roller 30; A second pressing roller 32 is arranged above the fifth guiding roller 31; A second roller frame 33 is arranged outside the second pressing roller 32; The second roller frame 33 is connected to the middle frame 2 through a second connecting bar 34; The second roller frame 33 is connected to the telescopic shaft of the fourth cylinder 35; A third adjusting roller 36 is arranged below the second cylinder 17.

[0024] As Figure 4As shown in the figure, a winding roller 37 is provided on the middle frame 2 and the left frame 1; a pressing rod 38 is further provided on the left frame 1; the pressing rod 38 is connected to the left frame 1 through a pressing member 39; one end of the pressing rod 38 is connected to the telescopic shaft of a fifth cylinder 40; a restricting member 41 is provided at the other end of the pressing rod 38.

[0025] By adopting the above technical solution: the second adjusting roller 30 can prevent the white film from wrinkling after plate pressing or film pressing, the fifth guiding roller 31 guides the white film, and after the telescopic shaft of the fourth cylinder 35 extends, the second roller frame 33 rotates around the second connecting bar 34, so that the transmission of the white film and the mother film is more stable. When only plate pressing is performed, the white film directly passes through the third adjusting roller 36 after passing through the fifth guiding roller 31, and then passes through the winding roller 37 below the third adjusting roller 36 and thus enters the white film winding device 7 for winding; when film pressing is performed, the white film and the mother film are separated through the winding roller 37 above the third adjusting roller 36 after passing through the lowermost fifth guiding roller 31.

[0026] After the telescopic shaft of the fifth cylinder 40 extends, the pressing rod 38 rotates around the pressing member 39, so that the restricting member 41 always presses the white film and the mother film during the winding of the white film and the mother film, thereby preventing the white film and the mother film from being fluffy during winding.

[0027] In summary, the present invention has the following beneficial effects: the present invention can perform film pressing and plate pressing. When plate pressing, nickel plates are provided on the first plate roller 10 and the second plate roller 14. When the white film passes through the cold area 27 on the first plate roller 10, no pattern is printed on the white film in contact with the cold area 27, and when passing through the second plate roller 14, the pattern on the nickel plate is printed on the white film in contact with the cold area 27 of the first plate roller 10. When passing through the first plate roller 10 and the second plate roller 14, the pattern on the nickel plate is printed on the white film to perform plate pressing on the white film. When film pressing is performed, no nickel plates are provided on the first plate roller 10 and the second plate roller 14. The white film and the mother film pass through the first plate roller 10 and the first moving roller 11, so that the pattern on the mother film is printed on the white film, and then through the second plate roller 14 and the second moving roller 15 for pressing again to complete film pressing.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
